Polymeric materials have been widely produced in the world industry in the last decades. These materials present various interesting properties such as high mechanical strength compared to their low density, toughness, corrosion resistance, electrical and thermal insulation and they are generally low cost. However, synthetic polymers cannot be included in the recycling system causing environmental problems. Functionalized biopolymers constitute a green alternative to the use of polymer derived from fossil fuel resources. The most used sub-class of biopolymers are polysaccharides like starch, cellulose and chitosan. Polysaccharides are biodegradable, low cost and abundant. In this project two different starch functionalization reactions were conducted: epoxidation and methacrylation.
